Step-by-step explanation:
3y^2 + 7y - 6
20+2N=52
now subtract 20 from each side, to get 2N alone
2N=32
now divide each side by 2
N=16
This is an exponential decay problem.
Using the equation Y = a *(1-rate)^time
where Y is the future value given as 12,000 and a is the starting value given as 13,000.
The rate is also given as 5%.
The equation becomes:
12,000 = 13,000(1-0.05)^x
12,000 = 13,000(0.95)^x
Divide each side by 13000:
12000/13000 = 0.95^x/13000
12/13 = 0.95^x
Use the natural log function:
x = ln(12/13) / ln(0.95)
x = 1.56 years. ( this will equal 12,000
Round to 2 years it will be less than 12000.
Answer:
sorry but idk
Step-by-step explanation:
4 = 400/100
or 400 hundreths
